Client Profile
The client is a Web3-based global payment gateway integrating stablecoins and cross-chain swaps. With over 200,000 daily active users and real-time settlements across Ethereum, Solana, and BNB Chain, the client faced threats from transaction fraud, smart contract abuse, and sudden spikes in network anomalies. Their security team lacked 24/7 visibility and a streamlined response mechanism for on-chain incidents.
Challenges Faced
Key security concerns included:
- No real-time monitoring of on-chain events and transaction anomalies
- Inability to detect and respond to smart contract abuse or frontrunning attacks
- Fragmented visibility across multi-chain operations and RPC endpoints
- Manual and delayed incident response to fund-draining exploits or transaction floods
Solution
COE Security delivered a Blockchain Monitoring & Incident Response Framework, combining:
- Real-Time Blockchain Event Monitoring: Deployed watchers for suspicious transactions, contract interactions, and token transfers
- Custom Alerting & Dashboards: Integrated multi-chain telemetry with SIEM dashboards and Slack/Webhook alerts
- Automated Incident Response Playbooks: Created blockchain-specific runbooks for DDoS, flash loan, phishing airdrops, and rug pulls
- Threat Intelligence & Forensics: Established on-chain forensics capability with trace and attribution tools
Operational Vigilance in Action
- Detected and flagged a flash loan exploit attempt within 3 seconds of execution
- Identified frontrunning MEV bot behavior siphoning platform fees
- Integrated on-chain logs into existing SOC tools for unified visibility
- Enabled early detection of scam token airdrops to users’ wallets
- Blocked a fake router contract interacting with platform tokens
Readiness, Governance & Strategy in Blockchain Environments
- Created a blockchain-specific Incident Response Plan aligned with NIST and ISO 27035
- Conducted tabletop exercises and threat simulation for Web3 scenarios
- Delivered training to SOC teams on DeFi-specific threat handling
- Built a cross-chain asset monitoring policy with governance checkpoints
